The problem of ambiguities inherent in the manifold of any linear array structure is
investigated. Ambiguities, which can be classified into trivial and nontrivial, depending on …

We address the uniqueness problem in estimating the directions-of-arrival (DOAs) of
multiple narrowband and fully polarized signals im**ing on a passive sensor array …

The so called universal steering vector (USV) whose locus is equivalent to the array element
pattern is applied to the direction of arrival (DOA) estimation by multiple signal classification …

The effect of the mutual coupling between the array elements on the performance of the
adaptive array antennas (AAA) is investigated when the actual received voltages which …

Although the properties of direction-finding (DF) algorithms have heen investigated
extensively, the fundamental effects of the array configuration on the performance of DF …

The manifold of a general two-or three-dimensional (2-D or 3-D) array of sensors is studied
using differential geometry. By considering the azimuth and elevation angles as the …

Sensitivity analysis plays an integral role in many engineering design problems. The
purpose of this paper is to investigate the direction finding sensitivities (DFSs) with respect to …

Different from phased-array, frequency diverse array (FDA) offers range-dependent
beampattern and thus provides new application potentials. But, there is a fundamental …

The element pattern reconstruction method is introduced to calibrate the mutual coupling
effect of the microstrip arrays. This method is based on the fact that if the reconstructed …

In this paper, we first derive an improved reflection model of arbitrarily polarized
electromagnetic (EM) waves for mirrored systems. Then, a mirrored linear vector sensor …
